` SPECIFICTION formng part of Letters Patent `No. 2881362, datedNovember 13, 1883,

To (LZZ whom, it may concern: i .v

Be it known that I, HENRY S. PALMER, o SantaAna, county of Los Angeles,State of California, have invented certain new and useful Improvementsin' Gang-Plows; and I hereby declare the following to be al full, clear,

and exact description thereof. d

My invention relates to the .class ofgangplows and to certain new anduseful improvements therein.

These improvements consist in' details of construction and in the meansfor leveling-and regulating the depth of the plows, as will hereinafterfully appear. y

The present construction of levers by which the cranks or crankTaXlesnpon which the wheels are mounted or operated renders it often a matterof some difculty to raise the plows out of the ground or regnlate theirdepth. gIt is the object of my invention to render this operation easy,-as I shall show. i d

Referring to the accompanying drawings, Figure 1 is a perspective viewof a gang-plow, showing my improvement. f Fig. 2 is a verti-` caltransverse section of the same.

`A represents the. beams-of the plow, and B the plows. O is the seat. dis an axle, D, mounted in suitableboxes or bearings, to oscillate. Upononeend of-the axle is rigidly secured a crank, E,'in the end of which isjournaled one wheel, F. Upon the other end of the axle is looselymounted or fitted a sleeve, e, carrying onits onter end a crank, E', inthe end of which is journaled the other wheel, F'. The inner'end of thissleeve carries a gear, G. Upon this side or end of the axle, between thegear G and the box of the axle, is fitted and secured, by a seti screw,h,.a verticallrack7 H. Pivoted to the body of this rack, at i, is asegmental gear, I,

`- the teeth of which mesh with the gear G. This segmental gear isprovided with a` handle or lever, J, having a ,spring-pawhj, whichengages with the rack H. Upon the other end of the axle, between its boxand the crank, is

i keyedj securely a gear, K: i i

Upon a frame-work of the seat orybeams is i rigidly Secured a rack, L,to whichV is pivoted the body of a segmentalgear, M, the teeth of Underthe beams Application file April io, issa. (No man.)

which mesh with the teeth of gear K. It has a handle or lever, N,provided With a springpawl, (n, engaging withthe rack L. d

The Operation of these `devices is as follows: By moving the lever N theaxle is oscillated and both cranks moved alike, to level the plows. This`movement is occasioned by reason of the gear K and the rack H on theother side being fast on the axle, and `the lever J beingengaged withtherack H, through, its v pawl j, and the segmental gear I, meshingwiththe loose gear G on the sleeve e, which carries crank E'. Thus bothcranks receive, niotion from the axle equally. The rack H, by` beingonthe axle, isalways in position to be engaged by the lever J. N ow, whenthe lever .I is moved, the axle is not oscillated, and only the crankE,` is moyed, `which regulates the` depth of the plows. This movement iseffected by reason of the loose sleeve e, with Whose gear G thesegmental gear I of the lever J engages. But small exercise of power isrequired to move either of the levers to level the plows or regulatetheir depth.`

I am aware that heretofore wheel and sulky plows have been provided witha loose crank set and held by a lever and with another lever by whichthewhole aXle is turned to raise and lower the frame. I am also aware thatsuch by means of a pinion and a segmentlever; hence `I do not claim sucharrangements, broadly.

Having thus described my invention, WhatI claim as new, and desire tosecure by Letters Patent, is-

The combination, in a gang-plow, of the axle D, formed at one end withthe fixed crankE `Operations have been previously accomplished and rackL, with the loose sleeve ve, having the crank E' and pinion G, therack-standard H, and the segmentdever J, these parts being .adjustablySecured/to the axle, substantially as and for the purpose set forth.

In witness whereof I hereunto setmy hand.
